These are incredible for hiking, hunting, etc

One alone won't be able to do much but if you need to connect a few people in a rural area it's amazing.

My only hope is that waterproof models become more available

If OP is attempting a 3-2-1 Backup scheme, this is an irrelevant argument.

OP wants to store a backup in a different physical location while trusting that it won't be used to train AI. They are looking for services that can satisfy that.

Welcome to GoodBerry, Home of the GoodBerry. can I take your order?

Blue light has a documented effect on our circadian rhythm and melatonin production. It's been studied quite a bit. I'm sure mental overstimulation is a component, but it absolutely is not the whole story.

In Western society, there is a big focus on silver bullet solutions because people don't want to address issues in a holistic way. Thus, you have blue light filters instead of turning the screen off.

Of course a 6" screen doesn't produce as much as a ball of nuclear fire

But that ball of fire isn't 12 inches from your face at midnight. And, the majority of blue light filter use is targeting sleep quality. A good portion of this comes down to cumulative exposure time. The best solution is to just not look at screens after a certain hour, but no one wants to do that.

What model pi? How responsive do you find it?

Sure, and I should've been more clear and said people need to understand what the Fediverse is.

This is, ultimately, about what federation means and how this platform operates. Its deficiencies, and the way things work currently to address those deficiencies. What I have posted is just as true for kbin as it is for lemmy.

I do, personally, think it's reasonable for an instance to have "private" communities exclusive to their own users. This is likely a subject that comes down to personal belief, but after dealing with so many trolls and bad actors on other platforms, I absolutely do see a need to have those kinds of permissions.

People need to understand what lemmy is. This is not monolithic social media like facebook or reddit. People need to understand that, or the mismatch between how they think it works and how it actually works is going to cause a lot of mental anguish that could be avoided.

As they say in software development, 8 hours of debugging can save you from one hour of reading the manual.

When a Lemmy.World user posts to a Beehaw community right now, it updates the cached community that Lemmy.World stores. Beehaw has defederated with them, so the "source of truth" (hosted by Beehaw) never updates. The source of truth is what updates other federated instances. As a result, someone on startrek.website, for example, will not see posts made by lemmy.world users to beehaw communities. The only people who can see what lemmy.world users post to beehaw right now are other lemmy.world users.

It's not my intent to determine how things "should" work.

This is how things DO currently work.

I don't think that assertion is based in reality. A server has to be hosted somewhere, and admins will generally choose to uphold those local regulations for the sake of their instance's own longevity. Federation has never meant that you communicate with literally every other instance. This isn't Tor where nodes pass along communications that don't directly involve themselves.
